AUTHENTICATION SYSTEM AND AUTHENTICATION METHOD FOR PERFORMING AUTHENTICATION OF WIRELESS TERMINAL
First Claim
1. An authentication system for performing authentication of a wireless terminal that issues an authentication request to an authentication server connected to a communication network through a wireless base station for access to the communication network, whereinthe wireless base station comprises:
- authentication information acquisition means for acquiring authentication information from a wireless connection request packet including the authentication information transmitted from the wireless terminal; and
authentication request transmission means for transmitting the authentication information acquired by the authentication information acquisition means and RAS unique information which is information unique to the wireless base station that has previously been registered in the wireless base station to the authentication server as an authentication request packet,the authentication server comprises;
base station information acquisition means for acquiring the authentication information and RAS unique information of the wireless base station from the authentication request packet transmitted by the authentication request transmission means; and
base station information determination means for comparing the authentication information and RAS unique information acquired by the base station information acquisition means with wireless terminal authentication information in which the authentication information and RAS unique information have previously been registered in association with each other to determine whether or not they coincide with each other, andin the case where the acquired authentication information and RAS unique information and previously registered wireless terminal authentication information coincide with each other, the base station information determination means authenticates the wireless terminal.

Abstract
An authentication system for performing authentication of a wireless terminal is a system that issues an authentication request to an authentication server connected to a communication network and includes a wireless base station and an authentication server. The wireless base station includes: an authentication information acquisition means for acquiring authentication information from a wireless connection request packet; and an authentication request transmission means for transmitting the authentication information acquired by the authentication information acquisition means and RAS unique information registered in the wireless base station to the authentication server. The authentication server includes a means for acquiring the transmitted authentication information and RAS unique information and comparing the acquired authentication information and RAS unique information with previously registered wireless terminal authentication information previously registered to determine whether or not they coincide with each other. In the case where the acquired authentication information and RAS unique information and previously registered wireless terminal authentication information coincide with each other, the wireless terminal is authenticated.

6. An authentication method used in an authentication system for performing authentication of a wireless terminal that issues an authentication request to an authentication server connected to a communication network through a wireless base station for access to the communication network, comprising:
-
a first step in which the wireless base station acquires authentication information from a wireless connection request packet including the authentication information transmitted from the wireless terminal; a second step in which the wireless base station transmits the authentication information acquired by the first step and RAS unique information which is information unique to the wireless base station that has previously been registered in the wireless base station to the authentication server as an authentication request packet; a third step in which the authentication server acquires the authentication information and RAS unique information of the wireless base station from the authentication request packet transmitted by the second step; and a fourth step in which the authentication server compares the authentication information and RAS unique information acquired by the third step with wireless terminal authentication information in which the authentication information and RAS unique information have previously been registered in association with each other to determine whether or not they coincide with each other, wherein, in the case where the authentication information and RAS unique information acquired by the third step and previously registered wireless terminal authentication information coincide with each other, the fourth step authenticates the wireless terminal. - View Dependent Claims (7, 8, 9, 10)

-
12. An authentication server which is connected to a communication network to which a wireless terminal is connected through a wireless base station, comprising:
-
base station information acquisition means for acquiring authentication information and RAS unique information of the wireless base station from the authentication request packet transmitted by the wireless base station; and base station information determination means for comparing the authentication information and RAS unique information acquired by the base station information acquisition means with wireless terminal authentication information in which the authentication information and RAS unique information have previously been registered in association with each other to determine whether or not they do not coincide with each other.
